Web Tension & Guiding
Improved web tension loadcell flange mount helps with installation
TTS Systemshas been producing web tension loadcells since 1997, with various updates and improvements along the way. The latest is a re-design of the flange mount for the CRL and CRF cartridge transducers

cartridge transducers are available in two shaft choices - the CRL with a live rotating bearing head and CRF with a fixed head, both designs
he design change allows the transducer to be easily rotated to achieve the best mid wrap
allow for shaft end float, thus reducing any load misalignment or side loading. Measurement capacities from 100N to 5,000N, the full strain gauge bridge
configuration has an output range of 2mV/V and offered with either an M12 or Amphenol connector. The newly improved flange mount is the result of via customer feedback program, listened and responded, improving the tension measurement loadcells and
instrumentation products to meet the client’s exacting needs. This is matched with TTS’s custom designed transducer service – mounting assembly, shaft diameter / length, connector type / location, output, etc. Contact our design team today with your application requirements:

built into each roll end, the Tension Roll transducer is suitable for installation on original equipment or for retrofits since it arrives pre- assembled and ready-to-install between the facing sides of a machine frame. It can be inserted into an appropriate web path location, and an accurate web tension value can be displayed on a connected indicator or controller.
NO ASSEMBLY REQUIRED With the TR transducer the engineering time required to size the unit to the machine frame prior to installation is significantly lower than when installing standard shaft-end load cells or tension transducers onto an idler roll. Another advantage of the Tension Roll transducer over a conventional idler roll with transducers is that it requires only a single transducer cable to connect at one end of the roll. The transducer's connector cable never has to cross the machine. For web presses and machines that run an

extreme range of materials and tensions, the Tension Roll transducer can be mounted in a pair of DFE's model C shaft-end tension transducers . This allows one range of tensions to be measured by the Tension Roll's sensors, while a higher load range can be measured using the externally- mounted tension transducers. This feature is convenient in the rare cases that a machine's tension range exceeds the 100:1 maximum-to- minimum tension ratio of DFE's extended range option. The Tension Roll transducer is available with
three standard roll materials, including aluminum, steel or stainless steel. Special roll surface materials are available. The standard overload capacity on the largest unit is 3,000lbs (13,300N). Roll face width is sized individually (from 6-inches [152mm] up to 120-inches (3.0m) to fit almost any
TENSION ROLL TRANSDUCERS CAPABILITIES • Transducers and idler roll in one unit • Fast, hassle-free installation-like any dead-shaft idler roll
• Aluminum, steel or stainless steel rolls in many surface finishes • Now available in three frame sizes plus many custom variations • One electrical cable
Just specify your desired shaft length, load rating, roll diameter and any options or a special roll
finish.This is faster, easier and less expensive than installing a separate idler roller with two transducers (a.k.a load cells). Only one transducer cable is used, meaning there is no cable- crossing between machine frames. Aluminum, steel or stainless steel rolls are available in many surface finishes.
